Which hormone stimulates osteoclasts in the raising of calcium levels in the blood?

If you are looking for the one hormone that does this, then the answer is parathyroid hormone (PTH), produced in the parathyroid glands.
A more technical description is given below:
Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands. The first, 1,25-Dihydroxycholecalciferol (active vitamin D3), serves to increase calcium absorption from the intestine. The second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed ("reabsorbed") into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.

∙ 9y agoThe hormone involved in raising the concentration of calcium ions in the blood plasma is parathyroid hormone (PTH). PTH is secreted by the parathyroid glands, which are located immediately adjacent to the thyroid gland. Osteoclasts are cells that resorb bone, in the process releasing calcium into the blood. However, osteoclasts lack a PTH receptor, and the hormone has its direct effect on the osteoblasts by binding to them. The osteoblasts respond by raising their production of a molecule called RANKL, which in turn stimulates the development of osteoclasts and so increases the resorption of bone and release of calcium into the blood. PTH also raises blood calcium by:
stimulating the small intestine to absorb more calcium
stimulating the tubules of the nephrons to reabsorb more calcium

∙ 14y agoParathyroid hormone affects calcium levels in the blood. When the parathyroid glands sense hypocalcemia (low blood-calcium), they release more parathyroid hormone, which causes the bones of the body to release calcium into the blood. Calcium is very important for all muscle contractions in the body, and initiation of heart muscle cell depolarization (which begins the chain of events that leads to a heartbeat).

Osteoclasts in bone tissue have the effect of raising calcium levels in the blood What?
Osteoclasts break down bone, which will essentially increase the amount of free calcium in the blood stream. Osteoblasts "build" bones from the free calcium in the blood. Calcium is involved in muscle contraction, so if you lack the necessary calcium in your diet, your body will actually break down bone material in order to obtain the necessary calcium for proper muscle function.
What hormone increased the amount of glucose in the bloodstream?
Amylin
What is bone synthesis?
Precipitation of the salt calcium phosphate among fibers of the protein type I collagen. This results from raising the concentrations of calcium ions and phosphate ions beyond their "solubility product" concentration. This occurs next to special cells called osteocytes, and not inside their cytoplasm. Nobody has discovered the mechanism by which osteocytes pump high concentrations of calcium ions and also high concentrations of phosphate ions into the same locations. One theory is that a special protein ("osteoid") binds to both calcium ions and phosphate ions, so that they precipitate at concentrations that would not be high enough to cause precipitation if no osteoid were present. If you know how osteocytes cause bone synthesis, then you should publish this information in a refereed journal, such as Nature. akharris@bio.unc.edu
What is Glycagon?
Glycagon is a 29 amino acid polypeptide and is an extremely potent hyperglycemic agent. It's a hormone that is produced from alpha cells in the pancreas. Its target is the liver, where it promotes the: 1) break down of glycogen to glucose 2) synthesis of glucose from lactic acid and from noncarbohydrate molecules 3) release of glucose into the blood by liver cells, raising blood glucose levels

What stimulates the production of thyroxin?
Low blood calcium levels stimulate the parathyroid gland to produce parathyroid hormone (PTH). PTH stimulates the osteoclasts to break down the bone matrix releasing the trapped calcium thereby raising blood calcium levels.
How does the body regulate calcium?
The parathyroid glands, of which there are four, and the thyroid gland are the glands that produce hormones that regulate calcium levels in the blood. Two parathyroid glands are located on the surface of the thyroid, and the other two are either on the surface or buried inside. The parathyroid produces parathyroid hormone (PTH), and the thyroid produces calcitonin. Parathyroid hormone increases calcium and calcitonin decreases calcium. Parathyroid hormone (PTH) works with vitamin D to regulate the amount of calcium that goes into bone and teeth and floats around in the blood. Normally about 90% of your body's calcium is in your skeleton. Parathyroid hormone activates the osteoclasts to break down bone. thereby raising Ca2+ levels in the blood. Calcitonin inhibits osteoclasts, decreases intestinal absorption of Ca2+, and limits renal tubular reabsorption of Ca2+ allowing it to be voided in urine. In this way, the action of calcitonin decreases blood calcium levels.
What hormone is used to convert glucose into energy?
Cortisol stimulates the breakdown of protein into glucose, raising blood sugar, thereby providing more energy to deal with stress.

Adrenaline.
Is glucagon on positive feedback?
No Glucagon is a hormone produced by the alpha cells in the pancreatic islets of Langerhans that stimulates gluconeogenesis in the liver and stimulates the release of FFA (free fatty acids) from TG (triglycerides) to use it as a fuel, instead of glucose, in the other two process of cellular respiration (Krebs Cycle and electron transport chain) to produce energy, by doing so, it conserves and produce glucose at the same time; therefore raising the blood sugar level when it is low. It shows a negative feedback because the response negates the stimulus to maintain homeostasis.
What effect does calcium have on the heart rate?
The resting membrane potential is maintained by the distribution of positive and negative charged ions across both sides of the cell membrane. At rest, calcium concentration in cells of the heart is low as compared to the outside. At action, calcium channels in the membranes open, thereby allowing calcium to rush into the cells. So raising the heart rate.

Explain how antidiuretic hormone can help regulate hypotension Be specific?
it can help by increasing reabsorption of water by the kidney. With the reabsorption, blood plasma volume increases, thus raising blood pressure

What hormone makes your blood glucose increase?
The main hormone resposible for raising blood sugar is Glucagon. However, in times of stress, other hormones such as Cortisol and adrenaline may also play a role.
